Shoes, of which the following isa specifica tion.

This invention relates to devices "for applying, cementitious fluid ,materialtm the; portions. of a shoe. requiring such treatment during the manufacture thereof.

The object of the invention is to supply a device that operation and that. will supply cementitious fluid to the parts and only to the parts where it .is required; as for, instance, in these-called McKay shoewherein the sole is first channeled around its edge and the lip 'of the channel turned back upon the sole, and the sole and the upper'then united by stitching, the stitches beingplaced in the channel and the lip thereof must then thereof, whether. or

operated upon.

be replaced to cover the otherwise exposed stitches.

In order to insure the retention of the lip in its place, the cementitious fluid is used,

and is generally applied by hand in a slow.

and ofttimes unsatisfactory manner. The object of this invention is to so place and control the operation of I devices as to enable the operator to evenly,

accurately, and speedily with one movementof the shoe in one direction, complete the operation of applying the cementitiousfluid.

It is obvious that this device may be used with equally good results on welt shoes or or in any work wherein the cementitious fluid is required to be applied to the work adjacent the edge regular or irregular contour.

Other objects of inventionwill bev further pointed .out in the specification and the claims hereunto annexed. 7 Of the drawings: Figure 1 is a left side elevation partially broken away,'with a shoe in position to be Fig.2 is a part plan view of the device below the line 22 on Fig. 1.

Patented Feb.- W, 191 to reservoir or container 11 adapted to receive cement tious fluld, said container belng of 10 is a suit- .such construction as to permit the material therein to be heated to a given temperature as by means of a steam jacket 12. Below the container 11 and rigidly secured to the overhanging arm or bracket 13 to which are pivoted at 14111119 arms 15 under the control of springslG.

one of the distributers to be de standard to which is rigidly secured the Adjustably attached to;v the arms"1 5 near the ends thereof are the revoluble brushes or distributers 17 mounted inbr'ackets 18 adjustably secured to the arms 15 by means of screws 20.- The brushes 17 (see Fig. 4) have portion or holder 21 shown as set screwed to a revoluble sleeve 22 depending from the sheave 23, said sleeve 22 having a running fit in the bracket 18, the sheaves 23 being driven preferably in the direction of the arrows a on Fig. 2 by the straight and cross belts 24-25 respectively, and the belt 26 (see also Fig. l). The sheave 23 and sleeve 22 are bored as at 27 to" loosely receive a centrally bored stem 28 provided intermediate its ends with a valve 29 adapted to be closed when the brushes are to be removed or replaced a to the escape of the fluid. The brush proper is so constructed as to leave an openlng through its center as at 30 which is in register with the bore of the stem 28, said opening providinga passage for the fluid to reach the surface of the work where it will .be evenly distributed by the relative bodily movement of the brushes 20 the rotary movement of the said brushes The container 11 has underside a slide valve'31 having a Y con fitted to it at its nection 32 to which the flexible conduits 33 are attached, the other ends The arms or carriers 15 have-pivoted to of which are 7 tance as to hold the work in operative contact with theb'rushes 17 If, howe'ver, greater pressure is required on the work,'the guide disks 34 being slidably mounted on-their pivots 35. will .permit of the work being I pressed toward 'th ator.

As it isdesirable to eliminate waste of the,

brushes 17 to the satisfaction of the opercementitious fluid between operations, a con-. 'trol device is provided that starts the flow of fluid when the work is presented to the machine, and when the particular operation is completed the said control automatically stops the flow of fluid to the brushes 17.

. which is indicated by To thus control the flow of the fluid the valve 31 is provided with a spring pressed stem having the collars 36 fast thereon, and between which the bifurcated end of a lever 37 is positioned, said lever 37 being pivoted at 38 to an extension of the bracket 13 (see Fig. 1) and at its lower end has mounted thereon the roll 39, the normal position of dotted lines (Fig. 1), that being the position the roll will assume,

'1 and the valve 31 will be closed, due to the absence of work beneath the roll and the expansion of the spring encircling the stem of the valve 31.

When work is presented to the machine, it mustflrst contact with the roll 39 before reaching the guide disks 34and brushes 17,"

and in the placing thereof the lever 37 will be tilted so as to move the valve stem against the action of its spring, and thereby open the valve 31 for the fluid to pass to the brushes .17;

Thejshoe shown in section in Fig. 3 is of the well-known McKay'type wherein. a

channel 40 is cut around the sole of the shoe and the lip 41 turned back upon thesole so that the stitches 42 uniting thesole and upper may be placed in the channel. As this lip must again be returned to its original position upon the completion of the.

stitching, it is necessary to coat the channel and the lip with a cementitious material or has heretofore been done by hand in a time wasting and slipshod manner, to the detriment of the work. i.

' It. is obvious that with a machine of this description, shoes of the McKay, welt, or stitchdown type may be very rapidly coated at thedesired place, as in this instance a narrow path or coating around the entire sole, with a direction towardlthe machine.

but one movement of the shoe in In other Word s, a back and forth motion of the shoe would not be necessary to accomplish the desired result, although it is not prohibited. It is also obvious that the operator is not obliged to use both hands, as it is not neces- 70 sary to turn the shoe to effect theproper operation of the coacting devices.

It is also obvious that various changes and arrangements might be made amounting to mechanical skill without departing from the; spirit and scope of this invention. It will be understood that in place of the guide disks 34, other means may be employed, such, for instance, as a form corresponding to the shape of. the shoe with suitable foln lowers to control the movement of the distributers.

It is believed that the many advantages of this invention will be fully understood from the foregoing description.

Having thus described my invention, I claim:

1. In a device of the class described, a plurality of revoluble fluid distributers the axes of which are arranged perpendicularly. to the work to be operated upon; carriers for said distributers adapted to be swung toward or from each other; means to rotate said distributers; means to swing said distributers toward each other; and means governed by the work to separate said distributers.
